Application
L-Cystine has been used to prepare stock solution which in turn is utilized for determining the L-cysteine and L-cystine in pharmaceutical preparations as well as in urine samples by using spectrofluorimetric flow injection method.
Biochem/physiol Actions
Cystine is required for the synthesis of glutathione that protects the cells from oxidative stress. A specific x(c)-cysteine/glutamate antiporter mediates cellular uptake of cysteine in exchange for glutamate. Inhibition of cysteine uptake induces toxicity in neuronal cells.
